Fastening structure for backrest and seat pad of leisure chair

ABSTRACT

A fastening structure for backrest and seat pad of a leisure chair includes two sets of foot support, a back support and a seat support. The back support and seat support are fastened together by means of two fastening elements and fasteners, then are fastened to the foot support. The back support and seat support engage respectively with a backrest sleeve and a seat pad sleeve which have coupling sections formed at two lateral sides and one end thereof. The backrest sleeve and seat pad sleeve have a checker type surface formed by braiding a plurality of belts in a stagger fashion to become an integrated pad member thereby to increase the strength of the backrest and seat pad, and make assembly and disassembly easier with less time and work.

BACKGROUND OF THE INVENTION

[0001] This invention relates to a fastening structure for backrest and seat pad of leisure chair and particularly a structure that is capable of increasing the strength of the backrest and seat pad of a leisure chair, and is easy to assemble and disassemble with less time and work.

[0002] A conventional leisure chair (as shown in FIG. 1) mainly includes a chair frame constructed by a back support A, a seat support B and two foot supports C. There are a plurality of braided belts E fastened to the back support A and seat support B by means of rivets D to form a back pad and a seat pad for people to seat thereon.

[0003] However when to assemble the foregoing leisure chair, the belts E must be threaded alternately on the back support A and seat support B, and be fastened to the back support A and seat support B by means of rivets D. The assembly and disassembly are difficult, and take a lot of time and work. Moreover, fastening of the braided belts E to the back support A and seat support B by rivets D is done in a point bonding manner between the belt E and rivet D. It is not a strong bonding method. After being used for a period of time or when the chair subjects to a heavy weight, the bonding between the belt E and rivet D tends to rupture or break down, and makes the chair become useless.

SUMMARY OF THE INVENTION

[0004] In view of aforesaid disadvantages, it is therefore an object of this invention to provide an improved fastening structure for backrest and seat pad of leisure chair that has an increased strength and is easy to assemble and disassemble, and may save a lot of time and work in assembly and disassembly.

[0005] To attain aforesaid object, the leisure chair according to this invention comprises two sets of foot support, a back support and a seat support. The back support and seat support are fastened to the foot support by means of a fastening element and a fastener. The back support and seat support engage respectively with a backrest sleeve and a seat pad sleeve which have respectively coupling sections formed at two lateral sides and one end. The backrest sleeve and seat pad are made by braiding a plurality of belts in a staggered fashion to form an integrated checker type pad member for seating people.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0013] Referring to FIGS. 2 and 3, the leisure chair according to this invention includes two sets of foot support 1, a back support 2 and a seat support 3. The back support 2 and seat support 3 are fastened together at two sides by two fastening element 33 and first fasteners 34, then the coupled back support 2 and seat support 3 is fastened to the foot support 1 by means of a second fastener 11. The foot support 1, back support 2 and seat support 3 are respectively formed by bending a piece of tubular member. The back support 2 and seat support 3 engage respectively a backrest sleeve 21 and seat pad sleeve 31 which have respectively coupling sections 211, 211′, 211″ and 311, 311′, 311″ formed at two lateral sides and one end. The coupling section 211 and 311 are stitched around the backrest sleeve 21 and seat pad sleeve 31 so that the backrest sleeve 21 and seat pad sleeve 31 become an integrated pad member. The backrest sleeve 21 and seat pad sleeve 31 have respectively a checker type surface formed by braiding a plurality of belts 4 in a staggered fashion. The seat pad sleeve 31 may have another end formed a second coupling section 312 for housing a reinforced rod 32 therein to increase the strength of the seat pad sleeve 31 when mounting on the seat support 3. The reinforced rod 32 has two ends each attached to a coupling element 321 for fastening to one end of the seat support 3 so that the seat support sleeve 31 may support heavier weight. By means of aforesaid construction, the backrest and seat pad will have a greater strength. Assembly and disassembly are easier, and also take less time and work.

[0014] Referring to FIGS. 4, 5 and 6, for assembly of this invention, dispose respectively the tubular members of the back support 2 and seat support 3 into the coupling sections 211, 211′, 211″ and 311, 311′, 311″ of the backrest sleeve 21 and seat pad sleeve 31, then put the reinforced rod 32 into the second coupling section 312 of the seat pad sleeve 31 for increasing the strength of the seat pad sleeve 31 when mounting on the seat support 3. The coupling elements 321 at both ends of the reinforced rod 32 may be fastened to two ends of the seat support 3 by means of a third fastener 322 thereby to provide more comfortable seating for users and also to increase the strength of the pad member. The assembly and disassembly are easy and may be done with less time and work. By remedying the shortcomings of the conventional leisure chairs, this invention may help to improve living quality of the users.
